When the chair sensor pad is connected, the pad triggers the monitor when weight is removed from the pressure pad alerting the caregiver to respond. The alarm automatically resets when the patient returns to the safe position, reducing false alarms. Pads work with virtually all major manufacturer’s alarm monitors. All pads are constructed with durable vinyl cover, moisture resistant and easy to clean and are designed without holes to increase their water resistance and lifespan. 45 day, 7"x15".
